It was party time in the backseat of their chauffeured car in Tokyo for Justin Bieber and Sofia Richie. The playful pair took a series of silly shots, which they promptly and proudly broadcasted on social media. See them here!

Before we go any further, did you know that Sofia Richie is Nicole Richie’s sister and Lionel Richie’s daughter? It’s such a small world.

Anyway, the impromptu black and white backseat photo shoot, which Justin Bieber, 22, and Sofia, 17, participated in, ranged from silly to dramatic and at one point Sofia pointed a finger pistol at Justin’s temple. Please Sofia, don’t shoot! His last single was sooooo good!

But in all fairness, it did give her a chance to showcase her cool jewelry and slick, black pedicure. Sofia looked every bit the gangsta moll with her silk bomber jacket and tight pony tail, while Justin rocked a black hoodie and white V neck. Justin also mugged for the camera with a big, goofy grin, while Sofia made a kiss-y face.

Bieber is currently visiting Japan for his two concerts at the Makuhari Messe in Chiba on August 13 and 14 as part of his Purpose world tour. He elected Sofia to be his travel companion.

Justin’s tour will end Nov. 29 at London’s O2 Arena after he completes performances throughout Europe, Scotland and England – where the tour is expected to end with a final show at London’s O2 Arena on November 29.
